> After bringing up a 578 node cluster with 13 dead nodes, 0 were reported on
> the new GUI, but showed up properly in the datanodes tab. Some nodes are
> also being double reported in the deadnode and inservice section (22 show up
> dead, 565 show up alive, 9 duplicated nodes).

> I've confirmed there are 9 nodes showing up in both deadnodes and livenodes.
